Litecoin will rise more for sure because of its benefits and services with instant payment around the world in which can be efficiently mined with consumer grade hardware. I predict that the value of Litecoin when hits to a bullsih market this 2018 would be $200 - $300.
Even if it will achieve growth again I doubt that it will rise to the biggest value it had last year. At the end of this year, we could see growth to the 200 dollars and that will be the top growth ideal for the cash-out. The future is unpredictable but growth is highly possible. I personally don't hold any LTC but had it and sold it when the time was right. Currently, I am only watching and observing the progress which has the bright future if the developers commit themselves even more into the coin development. LTC is dependant on the other top coin and because it cannot act alone. When the growth of the BTC begins it will pull the LTC also up and those who are long-term holders can make a significant amount of money if they hold LTC in their portfolio.
